You can tell if you piston is hitting the head turning it over by hand........But trust me, if it is running, the piston is NOT hitting the head.D88Elitehonda wrote:just put the 48mm bbk in i took head to machine shop and i ran about half a tank at 1/2 throttle i noticed alot of vibration from motor and how can you tell if piston is hitting head
